Gases : IDGasFromVelocity (8 Variations)
The following are graphs of molecular velocities versus the relative number of molecules for argon, chlorine, methane and xenon at 300K. Which graph is for argon?

Concept Maps for General Chemistry Boyd L. EarlTwo concept maps have been developed to represent the organization of the material in a first-semester general chemistry course. By providing these maps to students and referring to them in class, it is hoped that the instructor can assist students in maintaining a grasp of the "big picture" during the progress of the course.Earl, Boyd L. J. Chem. Educ.2007, 84, 1788.

Origin of the Formulas of Dihydrogen and Other Simple MoleculesAndrew WilliamsThe logic and experimental data are described with which chemists originally deduced the formulas of fundamental substances such as H2, H2O, Cl2, NH3, CH4, and HCl. It is argued that high school and first-year undergraduate students would gain substantially from exposure to this process.Williams, Andrew. J. Chem. Educ.2007, 84, 1779.

Monomer of KevlarWilliam F. ColemanThe WebWare Molecules for July are from the paper Modern Sport and Chemistry: What a Chemically Aware Sports Fanatic Should Know by Giffin, Boone, Cole, McKay and Kopitzke.
